Re: help with a new potential sailor
There was a legally blind couple who sailed the Pacific US/NZ about 5 years ago and did a blog on it. You might be able to track it down. I would have misgivings about it though.
There is a programme here where blind people regularly go out with a sighted person and race as I recall. I daresay there is a similar thing in the US, or by going to a Yacht club you may well find someone who will take you out and give you some experience.
